Wisair Moves Closer To Complete UWB Silicon
Wisair said Wednesday that it had released its first UWB chipset, lacking only a media access controller to begin enabling OEMs to ship the technology in final form.Wisair said Wednesday that it had released its first UWB chipset, lacking only a media access controller to begin enabling OEMs to ship the technology in final form. Wisair is part of the Multiband OFDM Alliance, a consortium of companies aligned around a particular ultrawideband standard. The Wisair solution, which includes the physical baseband chip (PHY) and the corresponding radio or RF chip, comprises two-thirds of the necessary components to bring UWB to market. The MBOA alliance is competing against a rival group headed by Motorola Inc. and Freescale Semiconductor, a Motorola spinoff. Both sides have reached a stalemate within the IEEE working group dedicated to hammering out a UWB standard, prompting the MBOA group to develop its own independent standard. UWB promises to be able to transmit up to 480 Mbits of data across a maximum range of 10 meters, using both USB and IEEE 1394 protocols.
Currently, the MBOA group has settled on a PHY specification, according to Serdar Yurdakul, a spokesman for the Israeli chip maker, in an interview. By the end of the year, the MBOA group hopes to have finalized a MAC specification, so that Wisair can ship a full chipset to commerical partners by the second or third quarter of next year, Yurdakul said.
